Since the headphones are Bluetooth-enabled, they can connect wirelessly [6]to MP3 devices, cell phones–anything with Bluetooth capability[7]. That means you can chat with your friends and rock out to music without moving a muscle. The Q-Sound headphones can also connect to any audio device with a 3.5mm jack.

Each earphone contains two rechargeable [8]lithium-ion batteries to hold power derived from the Q-Sound’s solar panels. A single hour of sun [9]provides 2.67 hours of power [10]at maximum volume, and a fully charged headset can run for 40 hours.

Stephen hasn’t hinted at whether the Q-Sound will come to market, but we think it would be a hit among eco-savvy[11] athletes, beach-goers, and anyone looking to untether their tunes from the grid.
